Brake Test

  1. Full time AWD 6MT (except for STI model)
    1. Perform this test after driving the vehicle 2 to 3 km (1.24 to 1.86 miles) on road in order to stabilize the viscous torque of viscous coupling.
    2. Keep the front or rear wheels on the ground for this test.
      NOTE: Effect of the viscous torque on braking force will be added approx. 25 kg compared with FWD model.

    3. When the brake dragging force is large.
    • Check the dragging of brake pad or brake shoe.
    • Since it may be affected by the viscosity of viscous coupling, jack up either of the front or rear two wheels to check the each wheel rotation condition with the viscous coupling affection removed.
  2. Full time AWD 6MT (STI model) and CVT model
    1. Keep the front or rear wheels on the ground during measurement.

    2. When the brake dragging force is large.
    • Check the dragging of brake pad or brake shoe.

    Specifications: 

      Braking force
    Rear wheel total 10% or more of load on front or rear wheels
    Difference between right and left wheels 8% or less of load on front or rear wheels
    Grand total 50% or more of vehicle weight at the time of test
    • When measurement is difficult to carry out because both of front wheels are locked, brake force measurement in this condition conforms to standard grand total.
